As we are to mortify inordinate appetites, so we are to mortify inordinate passions (Col 3:8): But now you also put off all these, anger wrath, malice; for these are contrary to the design of the gospel, as well as grosser impurities; and, though they are more spiritual wickedness, have not less malignity in them. The gospel religion introduces a change of the higher as well as the lower powers of the soul, and supports the dominion of right reason and conscience over appetite and passion. Anger and wrath are bad, but malice is worse, because it is more rooted and deliberate; it is anger heightened and settled. And, as the corrupt principles in the heart must be cut off, so the product of them in the tongue; as blasphemy, which seems there to mean, not so much speaking ill of God as speaking ill of men, giving ill language to them, or raising ill reports of them, and injuring their good name by any evil arts, - filthy communication, that is, all lewd and wanton discourse, which comes from a polluted mind in the speaker and propagates the same defilements in the hearers, - and lying: Lie not one to another (Col 3:9), for it is contrary both to the law of truth and the law of love, it is both unjust and unkind, and naturally tends to destroy all faith and friendship among mankind. Lying makes us like the devil (who is the father of lies), and is a prime part of the devil's image upon our souls; and therefore we are cautioned against this sin by this general reason: Seeing you have put off the old man with his deeds, and have put on the new man, Col 3:10. The consideration that we have by profession put away sin and espoused the cause and interest of Christ, that we have renounced all sin and stand engaged to Christ, should fortify us against this sin of lying. Those who have put off the old man have put it off with its deeds; and those who have put on the new man must put on all its deeds - not only espouse good principles but act them in a good conversation. The new man is said to be renewed in knowledge, because an ignorant soul cannot be a good soul. Without knowledge the heart cannot be good, Pro 19:2. The grace of God works upon the will and affections by renewing the understanding. Light is the first thing in the new creation, as it was in the first: after the image of him who created him. It was the honour of man in innocence that he was made after the image of God; but that image was defaced and lost by sin, and is renewed by sanctifying grace: so that a renewed soul is something like what Adam was in the day he was created. In the privilege and duty of sanctification there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free, Col 3:11. There is now no difference arising from different country or different condition and circumstance of life: it is as much the duty of the one as of the other to be holy, and as much the privilege of the one as of the other to receive from God the grace to be so. Christ came to take down all partition-walls, that all might stand on the same level before God, both in duty and privilege. And for this reason, because Christ is all in all. Christ is a Christian's all, his only Lord and Saviour, and all his hope and happiness. And to those who are sanctified, one as well as another and whatever they are in other respects, he is all in all, the Alpha and Omega, the beginning and the end: he is all in all things to them.

And have put on the new man - See on Rom 12:1-2 (note).

Is renewed in knowledge - Ignorance was the grand characteristic of the heathen state; Knowledge, of the Christian. The utmost to which heathenism could pretend was a certain knowledge of nature. How far this went, and how much it fell short of the truth, may be seen in the writings of Aristotle and Pliny. Christianity reveals God himself, the author of nature; or, rather, God has revealed himself, in the Christian system with which he has blessed mankind. Christianity teaches a man the true knowledge both of himself and of God; but it is impossible to know one's self but in the light of God; the famous γνωθι σεαυτον, know thyself, was practicable only under the Christian religion.

After the image of him that created him - We have already seen that God made man in his own image; and we have seen in what that image consisted. See the notes on Gen 1:26, and on Eph 4:23 (note), Eph 4:24 (note). Does not the apostle refer here to the case of an artist, who wishes to make a perfect resemblance of some exquisite form or person? God in this case is the artist, man is the copy, and God himself the original from which this copy is to be taken. Thus, then, man is made by his Creator, not according to the image or likeness of any other being, but according to his own; the image του Κτισαντος, of the Creator. And as the Divine nature cannot exist in forms or fashions, moral qualities alone are those which must be produced. Hence the apostle, interpreting the words of Moses, says that the image in which man was made, and in which he must be remade, ανακαινουμενον, made anew, consists in knowledge, righteousness, and true holiness.

And have put on the new man,.... Concerning which, and the putting it on; see Gill on Eph 4:24,

which is renewed in knowledge; this man, or principle of grace in the soul, is a new one, which never was there before; and there is a daily renovation of it in the spirit of the mind, by the Spirit of God; for as the outward man decays, the inward man, which is the same with this new man, is renewed day by day, increases in holiness and righteousness, grows in grace, and particularly in "knowledge"; light and knowledge of a man's self, of his lost state and condition by nature, of his need of Christ, and of his salvation, is what appears at the first formation of this new man; and the daily renovation of him lies in an increase of spiritual, experimental, and saving knowledge of God, and Christ, and divine things; and indeed, until a man becomes a new creature, he neither knows, nor is he capable of knowing, the things of the Spirit of God; so that this new man, or principle of grace, begins with spiritual knowledge, and is formed in order to it, and its increase lies in it:

after the image of him that created him; the new man; for this is a creation work, and so not man's, but God's; and is made not after the image of the first man, no not as innocent, and much less as fallen; but after the image of Christ, to which the elect of God are predestinated to he conformed, and which is stamped in regeneration; and more and more appears by every transforming view of Christ, and will be perfected in heaven, when they shall see him as he is, and be perfectly like him, who is not only the pattern, but the Creator of it, even the author and finisher of faith.

the new man--(See on Eph 4:23). Here (neon) the Greek, means "the recently-put-on nature"; that lately received at regeneration (see on Eph 4:23-24).

which is renewed--Greek, "which is being renewed" (anakainottmenou); namely, its development into a perfectly renewed nature is continually progressing to completion.

in knowledge--rather as the Greek, "unto perfect knowledge" (see on Col 1:6; Col 1:9-10). Perfect knowledge of God excludes all sin (Joh 17:3).

after the image of him that created him--namely, of God that created the new man (Eph 2:10; Eph 4:24). The new creation is analogous to the first creation (Co2 4:6). As man was then made in the image of God naturally, so now spiritually. But the image of God formed in us by the Spirit of God, is as much more glorious than that borne by Adam, as the Second Man, the Lord from heaven, is more glorious than the first man. Gen 1:26, "Let us make man in our image, after our likeness." The "image" is claimed for man, Co1 11:7; the "likeness," Jam 3:9. ORIGEN [On First Principles, 3:6] taught, the image was something in which all were created, and which continued to man after the fall (Gen 9:6). The likeness was something towards which man was created, that he might strive after it and attain it. TRENCH thinks God in the double statement (Gen 1:26), contemplates both man's first creation and his being "renewed in knowledge after the image of Him that created Him."
